The heater includes a housing A having a closed top and bottom and mounted at the front and rear of its bottom on spaced aligned caster l wheels or rollers B. The housing comprises a framel, which includes a pair of oppositely disposed spaced parallel upright front frame members I of angle-shaped cross section, a pair of oppositely disposed spaced parallel upri ht rear frame members 4 of angle-shaped cross sec- 5 tion, a pair of upper'spaced parallel side braces 5 of angle-shaped cross sections connecting the members 3 to the members 4, a rear upper brace 6 aligned with the braces i. of angle-shaped cross section and connecting the members 4 to- 10 gether, a front upper brace I aligned with the braces 5 of angle-shaped cross section connecting the braces 5 together rearwardiy of the members 3, a rear intermediate brace 8 connecting the members 4 together, and a pair of intermediate side braces 8 connecting the members 3 to the members 4. The braces I, i and 1 are arranged below the upper ends of the members I, l and they cooperate to provide a support for a purpose to be referred to.

The housing also includes a bottom wall 2, a top wall III, a front wall II, a pair of side walls l2, l3 and a rear wall l4, and the walls ll, l2, l3, l4 are suitably secured to and are disposed exteriorly of frame I. The walls II, I 2,

l3 and I4 do not depend below the lower ends of the members I, 4. The wall II is suitably secured to and is arranged between the upper ends of the walls II, l2, l3, II. The wall II is imperforate. Thewall II has its upper portion formed with an enlarged opening II. Each of the side walls is formed of two sections I6, I! (Figure 1) and with the section I'I formed with an enlarged opening it for receiving section Ii. The latter constitutes a door for closing the opening 18 and it is hinged at its lower end to section II, as at IS. A latch 20 is carried by section ll for releasably retaining section II in closed relation with respect to'opening II. The latter is arranged in upper portion of section I1. The section It is provided with a handle 2 I. The rear wall I4 has a portion thereof formed of a hinged door 2| and below'the latter with an enlarged opening 22 constituting an intake.

Arranged within the space 23 formed between the braces 5, i and I and the top wall", as well as being supported by such braces is a water tank 24 provided with an angle-shaped filling pipe 25, which extends through the rear wall at r tank 24 and opens into the latter. The pipe 25 extends outwardly through and then upwardly with respect to the upper portion of wall II. The upper end of pipe 25 has detachably secured thereon a safety valve device 21 (Figure 8).

The forward portion of the bottom 28 of the tank 24 is arranged forwardly of brace 1' and opens into the upper end of a vertically disposed radiator 29 arranged inwardly of and extendin across the opening I5. The lower end of the radiator 29 opens into a water receiver 39 arranged below opening I5 and inwardly of wall I I. The radiator 29 is positioned between brace 1 and wall II and depends slightly below the bottom of opening I5. The radiator is secured to the bottom of tank 24 and to the top of the receiver 38. The latter may, if desired, be secured to frame I. Disposed in forwardly extending relation with respect to the radiator 29 is a grating, lattice or screen 3| therefor. The grating is flanged, as at 32 and with the flange secured to the portion of the inner face of the wall H bordering the opening I5.

Arranged within the frame I and disposed in spaced relation with respect to the said front, rear and side wall, as well as being spaced from the tank 24 is a vertically disposed cylinder 33 having an open top portion 34 and an open bottom 35. The cylinder 33.is disposed rearwardly of the vertical axis of frame I, and includes a stationary section 36 and a hinged latchable section 31-, which is independent of the top portion 34. The latter -is integral with and disposed in lateral relation with respect to the upper end of the said section 36. Arranged within and having the major portion thereof disposed in spaced relation to the inner face of the cylinder 33 is a.

.vertically disposed water heating coil 38, The

upper end of the coil is arranged below the said top portion 34. The lower end of the'coil is arranged above the lower open bottom 35 of the cylinder 33. The upper and lower ends of the coil 38 are formed with substantial lateral extensions 39, 40 respectively which extend outwardly through the section 36 of cylinder 33 and are connected by the couplings 4|, 42 respectively to a hot water delivery pipe and a .water return pipe -43, 44 respectively. The pipe 43 leads from the extension 39 and opens into the tank 24. The pipe 44 leads from the receiver 30 to the extension 40. The pipe 43 extends through and is connected to the bottom of tank 24. The pipe 44 extends through and is connected to the rear wall of receiver 39. The extensions 39, 49, couplings 4|, 42, pipes 43, 44, bottom of tank 24, rear wall of receiver 30 and stationary part of cylin-' der 33 cooperate to suspend the cylinder within support and to-suspend the coil within the cylinders.

Arranged rearwardly of and in proximity to the radiator 29 is a motor driven fan 45 for forcing heated air through the radiator and grating for discharge from the front of the heater for. heating purposes. The fan hub is indicated at 46 and is connected to the shaft 41 of an electric motor 48 suspended in the support I rearwardly of'the fan 45.

The suspension for motor 43 includes a strap 49 formed at each end with a depending flange 5|) having an opening 5|. The strap 49 is secured to the lower face of the bottom 28 of tank 24 by the holdfast means 52'(Figure 6). The flanges 5| constitute hangers and depending therefrom is a V-shaped suspension member 53 formed of a bight 54 and a pair of oppositely outwardly inclined arms 55 having hook-shaped upper portions 56 for detachablyconnecting them to the flanges 5|. The body or the casing of motor 48 is seated intermediate its ends on the bight 54, and there is correlated with the latter a clamping means 51 for fixedly securing the motor 48 to member 53. The means 51 consists of a strap having an arcuate central portion 58 and a pair of oppositely outwardly inclined end portions 59, which bear against the inner faces of the arms 55. The bight 54 is substantially of semi-circular contour and constitutes a clamping part. The portion 58 of the means 51 also constitutes another clamping part. a The motor at one side is positioned against the bight 54, after which the portion 58 of the means 51 is positioned tightly against the opposite 'side of the motor, the end portions 59 of the means 51 are then secured to the arms 55 by the holdfast means 60 whereby the motor is clamped to said means 51 and suspended in support rearwardly of the radiator 29.

The cylinder 33 provides a heating chamber 6| for the cof. 38. There is correlated with the open bottom of chamber 6| a heating means for coil 38- and by way of example such means will be in the form of a regulatable self-feeding oil, liquid fuel or gas burner 62, The burner 62 is to be positioned on the bottom wall 2 of housing A, arranged within the support I, aligned with and extended to a point in close proximity to the open bottom of cylinder 33.

The heater includes a fan chamber 62 for the air and which is provided by an inclined partition I52 correlated with the walls I2, I3, radiator 29 and tank 24. The partition '62 extends at a rearward upward inclination fromthe receiver 30 to the cylinder 33 to a point below and in proximity to the end portion 39 of coil 38. The direction of the travel of the air is indicated by arrows, Figure 3. The direction of travel is such that the air will be pre-heated before it is expelled through the radiator by the fan.

The side wall I3 is formed with a plug 63 from which lead power circuit lines, not shown, to the motor 48. The plug 53 is adapted to be connected to a source of electrical energy, not shown. Connected to the wall I3.and communicating with the tank 24 is a temperature gage 64 and a water level gage 65 of the float operated type.

On the heating of the coil 38 a circulation of hot water will be had from the coil through respectively the tank 24, the radiator 29 and the receiver 30 and then through pipe 44 to the coil. As the fan is operating simultaneously on the heating of and during the circulation of the hot water the air drawn into the heater through opening 22 will be heated and discharged from the interior of the heater through the radiator 29 which also acts to heat the air.

What I claim is:

1. In a hot air heater of that type including a hot water circulating system for heating preheated air and a heating means for preheating air and the water of said system, the combination of a housing for enclosing and supporting said system and means, said housing having front and rear openings for the passage of air therethrough, the said front opening being arranged above the rear opening, inclined baflle means arranged within the forward portion of vthe housing, aligned with the lower portion of the front opening, extending above the height of said rear opening and coacting with the housing, said system and said heating means to provide a fan chamber .open at its front and rear, and a motor driven .unit including a fan in said chamber aligned with a housing formed with a cool air intake at its rear and a heated air outlet at its front arrangedpbove said intake, a hot water circulation system within the housing {or heating preheated air including a tank. a coil and a radiator opposing said outlet, heating means within the housing for preheating the incoming air and ior heating the water oi said system spaced rearwardly. irom said outlet. disposed below said tank and having said coil an ed therein, 81! upwardly disposed baille member inclining rearwardly from its lower to its upper end within the housing, said member being connected at its upper end to-said heating means, at its lower end with said radiator, said member coacting with said housing, said heating means and said tank to form an open rear and open front Ian chamber, a unit consisting of a motor driven Ian structure within said chamber and aligning with said outlet, and means secured to said tank for suspending said structure.
